技术领域technical field

本公开涉及动力手术装置。更具体地，本公开涉及包括套管针锁和套管针连接指示器的可重复使用手持型机电手术装置。The present disclosure relates to powered surgical devices. More particularly, the present disclosure relates to a reusable hand-held electromechanical surgical device including a trocar lock and a trocar connection indicator.

背景技术Background technique

用于执行如缝合术、痔切除术和粘膜切除术的手术程序的圆形缝合器械为众所周知的。这些装置包括砧座组件，所述砧座组件具有中心杆和支撑在中心杆上的砧座头。砧座组件的中心杆可附接到圆形缝合器械的套管针，其使得砧座组件能够线性平移。通常，在手术程序期间，将圆形缝合器械的工具组件插入组织的一个或多个管状区段中以连接组织区段或从组织区段内移除患病或受损组织。在手术程序之后，期望对圆形缝合器械进行再加工，以便使手术程序的总成本最小化。再处理通常需要经由高压灭菌等清洁圆形缝合器械。为了提高后处理的效率，需要套管针的可移除性。Circular suturing instruments are well known for performing surgical procedures such as suturing, hemorrhoidectomy, and mucosal resection. These devices include an anvil assembly having a center rod and an anvil head supported on the center rod. The center rod of the anvil assembly is attachable to the trocar of the circular stapling instrument, which enables linear translation of the anvil assembly. Typically, during a surgical procedure, a tool assembly of a circular stapling instrument is inserted into one or more tubular segments of tissue to connect tissue segments or to remove diseased or damaged tissue from within tissue segments. After a surgical procedure, it is desirable to rework the circular stapling instrument in order to minimize the overall cost of the surgical procedure. Reprocessing typically requires cleaning of circular stapling instruments via autoclaving or the like. In order to improve the efficiency of post-processing, the removability of the trocar is required.

因此，鉴于此，期望提供锁和指示器，所述指示器告知终端用户(例如，医生、护士、临床医生等)套管针适当地附接到下面的圆形缝合器械。Therefore, in view of this, it is desirable to provide locks and indicators that inform end users (eg, doctors, nurses, clinicians, etc.) that the trocar is properly attached to the underlying circular stapling instrument.

在使用中，当按下释放按钮275a时(例如在径向向内方向上，图15-18)，释放按钮275a相对于套管针组件270横向移动弹簧夹275b。在弹簧夹275b相对于套管针组件270横向移动时，弹簧夹275b的一对腿平移穿过一对锁销275c，使得在每个腿中的鹅颈管用以凸出和径向向外推动一对锁销275c。具体地，一对锁销275c被弹簧夹275b的一对腿的鹅颈管部分横穿，从其远侧部分过渡到其近侧部分。这样移动时，一对锁销275c中的每个径向向外推动的距离足以使一对锁销275c中的每一个澄清管状壳体272的相应开口272a，并且在一个实施例中，从外管206突出或与外管206的外表面齐平。预期，外管206可包括在其中形成的开口206a(见图15和图17)，所述开口206a与一对锁销275c中的每个对准。在一对锁销275c移开和澄清管状壳体272的情况下，套管针组件270可从适配器组件200的外管206的远侧末端内轴向缩回，或可插入到适配器组件200的外管206的远侧末端中。In use, when therelease button 275a is depressed (eg, in a radially inward direction, FIGS. 15-18 ), therelease button 275a moves thespring clip 275b laterally relative to thetrocar assembly 270 . As thespring clip 275b moves laterally relative to thetrocar assembly 270, a pair of legs of thespring clip 275b translates through a pair of lockingpins 275c such that the gooseneck in each leg is used to project and push radially outward A pair of lockingpins 275c. Specifically, a pair of lockingpins 275c are traversed by the gooseneck portions of a pair of legs of thespring clip 275b, transitioning from their distal portions to their proximal portions. In doing so, each of the pair of lockingpins 275c is pushed radially outwardly a distance sufficient for each of the pair of lockingpins 275c to clear thecorresponding opening 272a of thetubular housing 272 and, in one embodiment, from theoutside Tube 206 protrudes or is flush with the outer surface ofouter tube 206 . It is contemplated that theouter tube 206 may includeopenings 206a (see FIGS. 15 and 17 ) formed therein that align with each of a pair of lockingpins 275c. With the pair of lockingpins 275c removed and clear of thetubular housing 272, thetrocar assembly 270 can be axially retracted from within the distal tip of theouter tube 206 of theadapter assembly 200, or can be inserted into theadapter assembly 200 in the distal tip ofouter tube 206 .

一对锁销275c从外管206径向向外突起(或基本上与外管206的外表面齐平)向终端用户提供没有套管针组件270插入到适配器组件200的外管206的远侧末端中，或套管针组件270不适当地插入到适配器组件200的外管206的远侧末端中的视觉指示。当套管针组件270恰当地插入到适配器组件200的外管206的远侧末端中时，套管针组件释放机构的275一对锁销275c与套管针组件270的管状壳体272的相应开口272a对准并且进入其中(见图19)，以由此将套管针组件270锁定在适配器组件200的外管206的远侧末端内，并且由此向终端用户提供套管针组件270适当地插入到适配器组件200的外管206的远侧末端中的视觉指示。A pair of lockingpins 275c protrude radially outward from outer tube 206 (or be substantially flush with the outer surface of outer tube 206) to provide the end user with notrocar assembly 270 inserted distal toouter tube 206 of adapter assembly 200 A visual indication of improper insertion of thetrocar assembly 270 into the distal tip of theouter tube 206 of theadapter assembly 200. When thetrocar assembly 270 is properly inserted into the distal tip of theouter tube 206 of theadapter assembly 200, a pair of lockingpins 275c of the trocarassembly release mechanism 275 correspond to corresponding ones of thetubular housing 272 of thetrocar assembly 270Opening 272a is aligned and entered (see Figure 19) to thereby locktrocar assembly 270 within the distal tip ofouter tube 206 ofadapter assembly 200 and thereby provide the end user withtrocar assembly 270 as appropriate Visual indication of ground insertion into the distal tip ofouter tube 206 ofadapter assembly 200.

现在转向图20-23，在替代实施例中，适配器组件200可包括套管针组件释放机构1275。如所说明，套管针组件释放机构1275包括经由相应枢轴销1275e可旋转地支撑在支撑块(未示出)上和外管206中的一对释放按钮1275a。每个释放按钮1275a经由相应偏置构件1275d(例如片弹簧)偏置到锁定状态。Turning now to FIGS. 20-23 , in an alternative embodiment, theadapter assembly 200 may include a trocarassembly release mechanism 1275 . As illustrated, the trocarassembly release mechanism 1275 includes a pair ofrelease buttons 1275a rotatably supported on a support block (not shown) and in theouter tube 206 viarespective pivot pins 1275e. Eachrelease button 1275a is biased to a locked state via a corresponding biasingmember 1275d (eg, a leaf spring).

每个释放按钮1275a彼此相同，并且因此，本文将仅详细地描述一对释放按钮中的一个1275a。释放按钮1275a基本上为半圆形，绕枢轴销1275e延伸大约180°。释放按钮1275a限定远侧面或表面1275a'，偏置构件1275d的一部分与所述远侧面或表面1275a'接合，以向近侧推动释放按钮1275a，并且近端面或表面突出到尾部1275a"。释放按钮1275a的外表面可包括在其上形成的手指抓持特征(例如肋、滚花等)。Eachrelease button 1275a is identical to each other, and thus, only one of a pair ofrelease buttons 1275a will be described in detail herein.Release button 1275a is substantially semi-circular, extending approximately 180° aroundpivot pin 1275e. Therelease button 1275a defines a distal side orsurface 1275a' with which a portion of the biasingmember 1275d engages to push therelease button 1275a proximally and which protrudes to thetail 1275a". Release The outer surface ofbutton 1275a may include finger gripping features (eg, ribs, knurls, etc.) formed thereon.

释放按钮1275a在第一解锁位置和第二锁定位置之间可移动。如果或当套管针组件270不适当地插入到适配器组件200的外管206的远侧末端中时，释放按钮1275a通过套管针组件270从外导管206径向向外旋转或推动到第一解锁位置，由此向终端用户提供套管针组件270不适当地插入到适配器组件200的外管206的远侧末端中的视觉指示。当套管针组件270适当地插入到适配器组件200的外管206的远侧末端中时，通过偏置构件1275d旋转释放按钮1275a，使得其尾部1275a"接收在套管针组件270的管状壳体272的外表面中形成的凹座或凹口中(例如类似于管状壳体272的开口272a)，释放按钮1275a径向向内旋转或推动到第二锁定位置。当释放按钮1275a处于第二锁定位置时，向终端用户提供套管针组件270适当地插入和锁定到适配器组件200的外管206的远侧末端中的视觉指示。Release button 1275a is movable between a first unlocked position and a second locked position. If or when thetrocar assembly 270 is improperly inserted into the distal tip of theouter tube 206 of theadapter assembly 200, therelease button 1275a is rotated or pushed radially outward from theouter tube 206 by thetrocar assembly 270 to the first The unlocked position thereby provides the end user with a visual indication that thetrocar assembly 270 is not properly inserted into the distal tip of theouter tube 206 of theadapter assembly 200 . When thetrocar assembly 270 is properly inserted into the distal tip of theouter tube 206 of theadapter assembly 200, therelease button 1275a is rotated by the biasingmember 1275d so that itstail 1275a" is received in the tubular housing of thetrocar assembly 270 In a recess or recess formed in the outer surface of 272 (eg, similar toopening 272a of tubular housing 272),release button 1275a is rotated or pushed radially inward to the second locked position. Whenrelease button 1275a is in the second locked position A visual indication is provided to the end user that thetrocar assembly 270 is properly inserted and locked into the distal tip of theouter tube 206 of theadapter assembly 200.

在一个实施例中，参考图23，尾部1275a"包括倒角远侧表面，以便于当释放按钮1275a处于第二锁定位置时，在套管针组件270连接到外管206期间接收或通过套管针组件270。尾部1275a"另外包括基本上正方形的近侧表面，以阻止当释放按钮1275a相对于套管针组件270的管状壳体272处于第二锁定位置时套管针组件270从外管206缩回或断开连接。In one embodiment, referring to FIG. 23, thetail 1275a" includes a chamfered distal surface to facilitate receiving or passing the cannula during connection of thetrocar assembly 270 to theouter tube 206 when therelease button 1275a is in the second locked position.Needle assembly 270.Tail 1275a" additionally includes a substantially square proximal surface to preventtrocar assembly 270 from removing fromouter tube 206 whenrelease button 1275a is in the second locked position relative totubular housing 272 oftrocar assembly 270. retract or disconnect.

参考图1-9，在操作中，第一力/旋转传递/转换组件240用以推进/缩回适配器组件200的套管针组件270的套管针构件274，并且当砧座组件510连接到套管针构件274时打开/关闭再装载件400(图1)。具体地，当第一可旋转近侧驱动轴212由于第一连接器套筒218的旋转而旋转时，由于手柄组件100的第一联接轴124a(图2)的旋转，引起第二可旋转近侧驱动轴281旋转。第二可旋转近侧驱动轴281的旋转导致可旋转远侧驱动轴282的同时旋转。可旋转远侧驱动轴282的旋转引起联接构件286的同时旋转，这继而引起套管针组件270的驱动螺钉276的同时旋转。当驱动螺钉276在套管针构件274内并且相对于其旋转时，在套管针构件274和驱动螺钉276之间的接合(例如，螺纹接合)引起套管针构件274在套管针组件270的管状壳体272内的轴向平移。具体地，驱动螺钉276在第一方向上的旋转引起套管针构件274在第一方向上的轴向平移(例如，延伸或推进套管针组件270)，并且驱动螺钉276在第二方向上的旋转引起套管针构件274在第二方向上的轴向平移(例如，缩回套管针组件270)。当砧座组件510连接到套管针构件274时，套管针构件274在第一方向上的轴向平移导致再装载件400打开，并且套管针构件274在第二方向上的轴向平移导致再装载件400的关闭。1-9, in operation, the first force/rotation transfer/conversion assembly 240 is used to advance/retract thetrocar member 274 of thetrocar assembly 270 of theadapter assembly 200, and when theanvil assembly 510 is connected to Thetrocar member 274 opens/closes the reload 400 (FIG. 1). Specifically, when the first rotatable proximal drive shaft 212 is rotated due to rotation of thefirst connector sleeve 218, the second rotatable proximal drive shaft 212 is caused to rotate due to the rotation of the first coupling shaft 124a (FIG. 2) of thehandle assembly 100. Theside drive shaft 281 rotates. Rotation of the second rotatableproximal drive shaft 281 results in simultaneous rotation of the rotatabledistal drive shaft 282 . Rotation of the rotatabledistal drive shaft 282 causes simultaneous rotation of thecoupling members 286, which in turn causes simultaneous rotation of the drive screws 276 of thetrocar assembly 270. When thedrive screw 276 is within and rotated relative to thetrocar member 274 , the engagement (eg, threaded engagement) between thetrocar member 274 and thedrive screw 276 causes thetrocar member 274 to snap into thetrocar assembly 270 Axial translation within thetubular housing 272. Specifically, rotation ofdrive screw 276 in a first direction causes axial translation oftrocar member 274 in the first direction (eg, extending or advancing trocar assembly 270) and drivescrew 276 in a second direction Rotation of the trocar causes axial translation of thetrocar member 274 in the second direction (eg, retracting the trocar assembly 270). When theanvil assembly 510 is connected to thetrocar member 274, axial translation of thetrocar member 274 in the first direction causes the reload 400 to open and axial translation of thetrocar member 274 in the second direction This results in the closing of the reload 400 .

The second force/rotation transfer/conversion assembly 250 is used to fire the staples "S" ( FIG. 13 ) of the reload 400 for formation against theanvil assembly 510 .

在操作中，当第二可旋转近侧驱动轴214由于第二连接器套筒220的旋转而旋转时，由于手柄组件100的第二联接轴124c(图2)的旋转，引起第一联接轴251旋转，这继而引起行星齿轮组252旋转。行星齿轮组252的旋转引起钉导螺钉253的同时旋转。当钉导螺钉253旋转时，引起钉驱动器254轴向平移，这继而引起外部柔性带组件255轴向平移。当外部柔性带组件255轴向平移时，支撑基部255d按压抵靠再装载件400的钉驱动器组件(未示出)的驱动器适配器，以向远侧推进驱动器并且从再装载件400的钉仓(未示出)并且抵靠砧座组件510击发钉用于钉在下层组织中的形成。In operation, when the second rotatable proximal drive shaft 214 is rotated due to rotation of thesecond connector sleeve 220, the first coupling shaft is caused by rotation of the second coupling shaft 124c (FIG. 2) of thehandle assembly 100 251 rotates, which in turn causes planetary gear set 252 to rotate. Rotation of the planetary gear set 252 causes simultaneous rotation of thelead screw 253 . When thestaple guide screw 253 is rotated, the staple driver 254 is caused to translate axially, which in turn causes the outer flexible strap assembly 255 to translate axially. When the outer flexible strap assembly 255 is axially translated, the support base 255d presses against the driver adapter of the staple driver assembly (not shown) of the reload 400 to advance the driver distally and from the staple cartridge (not shown) of the reload 400. not shown) and fire the staples against theanvil assembly 510 for staple formation in the underlying tissue.
